1. Briefly describe the concept and importance of software quality. Software quality refers to the degree to which a software product or system meets explicit or implicit requirements. Its importance lies in that high-quality software can provide better user experience, higher reliability and security, and lower maintenance cost. In addition, with the intensification of market competition, only high-quality software can gain the trust and loyalty of users.

2. Explain the concept of software quality assurance and its main activities. Software quality assurance is a process and strategy to ensure that the software meets the expected quality standards in the whole development life cycle. The main activities include: formulating quality standards and plans, conducting requirements analysis, design review, code review, unit test, integration test, system test and acceptance test. In addition, it is necessary to monitor and improve quality assurance to ensure that quality standards are continuously met.

3. Explain the concept and purpose of software testing. Software testing is a process of evaluating the performance, function and security of a software system or code fragment by running it. Its main purpose is to find defects and errors in the software and ensure that the software meets the expected requirements and quality standards. Through testing, the reliability, stability and security of the software can be evaluated, and potential problems can be found and corrected, thus improving the quality of the software and the satisfaction of users.

Key points of software quality assurance and testing course:

1, the core position of quality assurance: The course emphasizes the core position of software quality assurance in the process of software development. Quality assurance is not only the detection of the final product, but also a way of thinking of participating in the whole process and preventing in advance to ensure that the software always meets the expected quality standards in the development process.

2. Purpose and method of testing: Software testing is considered as an important means of quality assurance. The course introduces various testing methods in detail, such as unit testing, integration testing and system testing. The purpose, application scenarios and implementation strategies of each test method are discussed in detail.

3. Tools and Automation: This course also covers tools and automation technologies used in modern software testing and quality assurance. These tools can greatly improve the efficiency and accuracy of testing and reduce human errors.

4. Thinking about continuous improvement: Quality assurance is not a one-off task, but a continuous process. The course emphasizes the importance of continuous improvement, and constantly optimizes the software development and testing process by collecting user feedback and analyzing error data.

5. Teamwork and culture: Quality assurance and testing are not only the responsibility of the technical team, but also the cooperation and support of the whole organization. The course also discusses how to establish a quality-oriented organizational culture, so that every member is responsible for the quality of the software.
